Measure the axial clearance
As soon as one of the parts listed in figure a. or the compressor housing isreplaced, the axial clearance definitely has to be checked (see fig. b).
- Measure with the cover for the face seal ring removed
- Attach the dial gauge to the crankshaft (item 3) using a measuring fixture.
- Place the calliper on the bearing flange (item 4).
- Move the crankshaft axially and keep the clearance constant.
Axial clearance < 0,15 mm
If the axial clearance is less than 0.15 mm, the bearing flange (item 4) must
be removed and a second gasket inserted (item 4.1, included in the kit,figure
c).
After fitting the second gasket (item 4.1) the axial clearance must be checked again.
